4 Claims; 1

The present invention relates to a device for peeling potatoes of thetype including a. container the inner side of'which is coated. with anabrasive substance, characterized in that. the

said container includes, on the one hand, a cylindrical-shaped partconstituting its side-wall and means owing tov which. said part can befitted inside a dish-washing machine, a machine of the type including afixed casing; in which rotates a screw placed below a dish-basket. andfitted on a driving shaft setin motion by av motor, after the saiddish-basket and the screw have been removed, and, on the other hand, acircularshaped plate constituting the bottom of the said container,means being provided forinterlocking angularly and ina detachable mannersaid plate and the driving shaft of the washing-machine.

The attached drawing represents, by way of example, an embodiment of thedevice according to the present invention.

Fig. 1 is a vertical section, according to'line I-I of the Fig. 2;

Fig. 2 is a plan view.

The device shown includes a container l the inner side of which iscoated with an abrasive substance 2. This container includes acylindrical shell 3 constituting its side-wall and a circular-shapedfloor plate 4, constituting the bottom of the container. Part 3 isfitted with means permitting it to be adjusted inside a dishwashingmachine. Said machine is of the kind comprising a fixed casing 5 inwhich rotates a screw placed below a dish-basket and fitted on a drivingshaft 6 driven by a motor. In the drawing, the said dish-basket and thescrew are supposed to have been removed. Means are provided for fittingpart 3 in the washing-machine. These means include four connecting limbs1 integral with part 3 and each one of which is, by one end, integralwith a stiffening ring 8 girdling the bottom of the said cylindricalshell 3, and a body 9 having a flange I0 on which is rivetted the otherend of each limb 1, said body having a locating or centering sleeve Hcooperating with a bearing sleeve [2 integral with the bottom I3 of thecasing 5. Furthermore, part 3 is provided with means owing to which itis capable of being immobilized angularl in the casing 5, said meansbeing constituted by a pm Hi secured to the ring 8 and cooperating withanother pin I5, secured to a flange inside the casing 5, so as toprevent any rotation from the cylindrical-shaped part 3 with respect tothe washing-machine.

Means are provided for making the circularshaped floor-plate 4 angularlyand in a detachable manner integral with the shaft 6. Saidmeansincludeby'wayof example, a square section hole; through the centreof the said plate 4,

cooperating with a correspondingly shaped part l1 oftheshaft 6. The endof shaft 6 is threaded to receive a nut It the purpose of which is toimmobilize axially the plate 4- on shaft 6.

The floor plate 4 is further provided with a depending cup 22, the sidewalls of, which are formed by a depending cylindrical flange 23 whichfits over the upper end of the locating sleeve H. The top wall of thecup is formed by a flange 24 extending inwardly from the top of saiddepending flange and terminating at the square section hole, said topwall resting on the upper ends of'thelocating sleeve H and bearingsleeve T2.

The cylindrical shell 3 includes, on its inner wall and close to thecircular-shaped plate re-v ferred to above, a thin metallic tongue I 8upraised" from the said inner wall, as shown in thedrawing, the purposeof which is to turn over the potatoes to be peeled.

The fitting. into the dish-washing machine, of the device described, isproceeded with as follows: After having removed the said dishbasket andthe screw, the cylindrical shell 3 is introduced inside the casing 5adapting at the same time the sleeve ll of the body 9 on the bearingsleeve [2 integral with the bottom 13 of the casing, the section 3 islowered until the flange l0 re ts on the said bottom l3. Thecircular-shaped floor plate 4 is then fitted onto the part I! of theshaft 6 and the nut i6 is tightened to keep said circular-shaped platein position, a disc I9 being preferably inserted between the plate 4 andthe said screw.

The working of the device described is the following:

The circular-shaped floor plate 4, rotating rapidly puts in motion thepotatoes which are in the container I, said potatoes being abraded asthey come in contact with the abrasive substance of the inner-wall ofthe container, the tongue l8 contributing to both the stirring of thepotatoes so as to bring each one of them against the abrasive substanceand the regular functioning of the device described.

It should be added that it is advisable to pour water in the container Iwhile the device is functioning, thus allowing of the ejection of thepaste caused by abrasion of the surface of the potatoes. Said ejectionis made possible by means of clearance' 20 which is between the plate 4and the inner wall of the cylindrical shell 3 as well as by means of anejecting aperture 2| provided in the bottom of the casing 5.

As it may be noted, this device which can easily be fitted into thewashing-machine of the type hereinbefore mentioned, has the advantage ofallowing to perform, with one single machine, two distinct operations:the peeling of potatoes and the washing of dishes, whence a sparing bothof room and money.

What I claim is:

1. A peeling attachment for use with a dishwashing machine of the typeincluding an open top casing having a rotary driving shaft extendingupwardly from the bottom wall, a bearing sleeve surrounding the shaft,and a removable dish Washing basket, said attachment comprising acylindrical shell having an inner abrading surface, a locating sleevespaced inwardly from said shell and extending below the lower endthereof, a plurality of spaced, radial limbs interconnecting saidlocating sleeve and the lower end of said shell, said locating sleevehaving an outwardly extending flange adapted to rest on the bottom ofthe casing to support said shell, interengaging means between said shelland said casing effective to prevent rotation of said shell, a rotaryfloor plate having an abrading upper surface and shaped to substantiallyclose the lower end of said shell and, means for establishing a drivingconnection between said shaft and said floor plate.

2. An attachment according to claim 1 in which the floor plate isprovided with a depending cylindrical flange shaped to fit over theupper end of said locating sleeve, and an inwardly extending flange atthe top of said depending flange to rest on the top of one of saidbearing and locating sleeves.

3. A peeler of the character described comprising an open top casinghaving a cylindrical bearing sleeve extending upwardly from its bottomwall, a rotary drive shaft extending upwardly through said sleeve; acylindrical shell spaced inwardly from the side walls of said casing andupwardly above the bottom wall thereof, said shell having an abradinginner surface, support means for said shell comprising a plurality ofangularly spaced limbs extending downwardly and inwardly from the loweredge of said shell, a support flange shaped to conform to the bottom ofsaid casing and connected to the inner ends of said limbs, said supportflange having a cylindrical locating sleeve shaped to fit over saidbearing sleeve; a rotary floor plate having an upper abrading surfaceand provided with a depending cup having side walls sleeved over theupper end of said locating sleeve, an upper wall resting on the upperend of one of said bearing and locating sleeves, and a central openingto receive the upper end of said shaft; and means for establishing adriving relation between said floor plate and shaft.

4. A peeler according to claim 3 including interengaging means extendingbetween said casing and said shell for preventing rotation of said shellin said casing.
